$a = get_defined_constants(TRUE);
foreach ($a as $k => $v) {
printf('%-25s <br/>', $k);
foreach ($v as $k => $v) {
printf('  --->%-25s %d<br/>', $k, $v);
}
}
this may look duplicate for previous anonymous post but that code snippet only return 1 for constants value
1-->first called the get_defined_constants by passing argument true to categorize the data
2-->then using foreach iterate over index of the array
3-->here printf is used to print title of the category
4-->then it move on to interrior array and display the list of contants available in each category along with its value

We can know sockets constants values with :
<?php
$a = get_defined_constants(TRUE) ;
foreach ( $a['sockets'] as $constant => $value ) {
printf("%-25s %d\r\n", $constant, $value) ;
}
?>
